Forktail Blenny (Meiacanthus atrodorsalis)

Add personality and vibrant color to your reef with the Forktail Blenny, also known as the Yellowtail Fang Blenny. This slender, active swimmer displays a striking contrast of a bright yellow head and tail with a sleek blue body. Its forked tail and graceful movements make it a standout in any saltwater aquarium.

Forktail Blennies are reef-safe and relatively peaceful, though they may defend themselves if threatened. They are well-known for their unique fang-like teeth, which help deter predators in the wild. In the home aquarium, they are hardy, fun to watch, and adapt quickly to captive foods.
